public class HepProgram
extends Object

HepProgram specifies the order in which rules should be attempted by HepPlanner. Use HepProgramBuilder to create a new instance of HepProgram.

Note that the structure of a program is immutable, but the planner uses it as read/write during planning, so a program can only be in use by a single planner at a time.
